Abstract Loop heat pipes with flexible transport lines are needed in some cryogenic applications as thermal links between cryocoolers and the cooled components for a variety of reasons such as vibration isolation, increased thermal transport distance, thermal diode function, multiple components, etc. This paper presents an innovative configuration of a cryogenic loop heat pipe designed to operate in the temperature range between 70 K and 140 K. The experimental data obtained for the loop heat with oxygen as a working fluid show that it reliably and predictably started in multiple tests and operated with the heat load range at the main evaporator from 0.5 W to 9 W with the main evaporator elevated up to 5 cm versus the condenser.
